su·per·string theory

(so͞o′pər-strĭng′)
A type of string theory in which both the particles that transmit forces (such as the photon, which carries the electromagnetic force) and the particles that make up matter (such as the proton) are viewed as string-like objects floating in space-time rather than point-like objects.

We start from a ten-dimensional action coupled with a dilaton (which is the bosonic component common to all superstring theories), which after dimensional reduction can be interpreted as a Brans-Dicke like theory [8].
The reality that quantum and superstring theories offer is the space she needs for her questioning of the relationship between the observer and the observed.
A summary of contemporary developments in gravitation theories will not be complete without mentioning Quantum Gravity and Superstring theories. Both are still major topics of research in theoretical physics and consist of a wealth of exotic ideas, some or most of which are considered controversial or objectionable.
Not knowing what to call it, Witten has dubbed it "M-theory." In one stroke, M-theory has solved many of the embarrassing features of the theory, such as why we have five superstring theories. Ultimately, it may solve the nagging question of where strings come from.
This fact has been demonstrated by the development of superstring theories in the 1980s even though these theories are based upon Klein's over-restrictive interpretation of Kaluza's five-dimensional model that forces the use of as many as 10 dimensions.

Finally, pressure to get a good value of G has quietly increased with the advent of superstring theories, ambitious Theories of Everything that attempt to explain all physics by setting the universe in a context of higher dimensions.
